Also known as: Orange ball tree
Most familiar varieties known as ‘butterfly bush’ have long, often mauve, purple or white flower heads. The globosa variety described here has small orange ball shaped fragrant flowers, hence its common name. Normally deciduous, but in warm, sheltered places semi-evergreen, it grows long slender branches, with long, pointed dark-green textured leaves covered with soft brown ‘wool’ beneath. It can be managed by hard pruning in late winter/early spring.
The common davidii varieties originate from China and can be found in gardens throughout Britain. They have lightweight seeds that disperse easily on the wind, allowing them to colonise roadside verges and waste ground. They invade important habitats and cause structural damage to walls and buildings, particularly along railways. Because of this, it is no longer recommended as a garden plant.
Buddleia globosa originates from the South American Andes and is believed not to have the same abilities of dispersal as its Chinese cousin. However, like other buddleias, they tolerate a wide range of moist well-drained soil conditions, and prefer full sun or dappled shade.
